Police and local authorities gave Maras information, access to interviews and the actual footage of Kasab after he was nabbed by the police. The transcripts submitted to court were also made available to Maras and his co-writer John Collee.

“We poured over thousands of pages of evidence from Kasab’s trial including witness statements, confessions and transcripts of satellite communications between the terrorists and their handlers. We interviewed Kasab’s lawyer for further insight,” Maras said.
